Abstract: Preparationed 100 hybrid combinations used sterile line of 10 three line japonica hybrid rice and 10 restorer lines in Heilongjiang Province, the influence of parents for hybrid combination on milled rice rate, chalky grain rate, chalkiness, gel consistency, amylose content, protein content were analyzed. The results showed that the female coefficient of variation of milled rice rate, gel consistency, protein content were larger than the overall coefficient of variation, the characteristics of hybrid combinations were mainly affected by female parents; the male coefficient of variation of the chalky grain rate, chalkiness and amylose content were larger than the total coefficient of variation, the male parents and the environment affected the percentage of chalky grain of hybrid combinations.  Milled rice rate, gel consistency and protein content was mainly affected by the female parents, the chalkiness degree was mainly affected by environment, the amylose content was affected by both parents and environment.
